where to find old ports.tar.gz files

[Jin Guojun [VFFS]]

I need to get wine 0.9.37 to 0.9.39 ports build structure, mainly the 
ports/emulatoes/wine/Makefile
to build these wine releases on FreeBSD 6.3-R, but I cannot find older 
ports.tar.gz files.

Does anyone know where I can find older ports.tar.gz files that contain 
wine 0.9.37 to 0.9.39 releases?

Thanks,
